ProtonMail is free encrypted email. Proton Mail is a service that provides easy to use secure email. ProtonMail's secure email system is designed around the principle of zero access. This means user data cannot be read by ProtonMail and turned over to third parties because ProtonMail.com servers do not store user encryption keys.

Besides the strong end-to-end, zero-access encryption of your email and contact data, ProtonMail has many useful features. For example, you can set an autoresponder, create a custom spam filter, and manage multiple email addresses in the same account. Emails that you send can be self-destructing, so they are automatically removed from the recipient’s inbox after a set time.

The dashboard is one of the slickest that you’ll find in a secure email service. With its modern inbox design, you can swap between column and row layouts, use conversation grouping, edit the toolbar, and use custom themes. Emails can be arranged into folders and labels, and you can use custom filters to organize your emails automatically. ProtonMail also has similar apps for Android and iOS.

ProtonMail offers three levels of support. Free users get limited support, Plus users get normal support, and everyone else gets priority support.
